A 4G smartphone from HTC has just hit the FCC and it could be the Thunderbolt which is destined for Verizon in the US. It's dubbed the PG05100, which was spotted at the WiFi Alliance way back in December of last year. This smartphone packs 700MHz LTE along with CDMA / EVDO connectivity so it could be the Thunderbolt. The thing is that this smartphone has a confidentiality request until March 31st and BGR just heard that this is going to launch in two weeks. Someone has to be wrong but if BGR happens to be right then this smartphone could actually be something that will be teased at MWC. Anyways, check it out at the FCC.
